Hi there!
My name is Bailey Dobier and I am a freelance graphic designer. Over the past couple of hours I have worked on various logos for both Black Rain and SoSoSexy, they are clean, fresh and effective- perfect for urban clothing lines such as these. The logos fulfil the criteria you specified in being black and white, and were created in Adobe Illustrator (this means you can scale the logos to the desired size without causing them to become pixelated and blurry).
If you wish to see a preview of these files (in .png format) contact me at: baileyodobier(@)gmail(dot)com or via freelancer.
The bid of $60 which I proposed is for both designs, i.e. $30 per design, however I am willing to negotiate prices slightly.
My previous experience includes designing logos for an online art gallery/ shop, alongside a social enterprise company.
As I have already drafted the logos, they are yours as soon as you need them :)
Thank you for your time,
Bailey Dobier
